Prosze o rozwiązanie zadanian w załączniku. Dokładne obliczenia.
e) .... = 1/5 * ∛(-16 : 2) - ∛(-72 : (-9)) = 1/5 * ∛(-8) - ∛8 = 1/5 * (-2) - 2 = -2/5 - 2 = - 1 i 3/5 = -1,6
f)
... = ⁵√(-128 : (-4)) + ⁷√(-128 : (-1)) = ⁵√32 + ⁷√128 = 2 + 2 = 4
d) .... = ∛(-9 * (-9)) : ∛(-3) - ∛(24 : (-3)) = ∛81 : ∛(-3) - ∛(-8) = ∛(81 : (-3)) - (-2) = ∛(-27) + 2 = (-3) + 2 = -1
